Data storage drive module carrier assembly

A data storage assembly comprising a plurality of removable data storage sleds, comprising:

• partition features configured to divide the data storage assembly into a plurality of bays each configured to hold an associated data storage sled;
• compression pins included in each of the plurality of bays to engage ejection springs of the data storage sleds;
• each of the plurality of data storage sleds comprising:
• a circuit card assembly comprising a plurality of connectors for coupling to drive modules and a host connector for coupling the data storage sled to an external connector;
• an enclosure comprising a plurality of apertures in the enclosure through which individual ones of the drive modules can be inserted into an associated connector on the circuit card assembly;
• drive module mounting assembles configured to hold the individual ones of the drive modules into the associated connector by at least including movable mounting features to accommodate varying lengths among the individual ones of the drive modules.
